Cryoplasty for Arterial Restenosis

Objective A prospective follow-up study of patients with arterial restenosis undergoing cryoplasty. Materials & methods Between May 2004 and June 2005, 10 patients with restenosis following ilio-femoral endovascular treatment underwent twelve cryoplasty procedures. All patients had had at least one previous episode of stenosis treated by conventional endovascular methods and had suffered further restenosis. The indications for treatment were grafts at risk (n = 5) and symptomatic in-stent restenosis (n = 5). Two patients underwent re-cryoplasty. Cryoplasty was performed in accordance with manufacturer's instructions using 6-8mm balloons. All patients had Doppler ultrasound evaluation at 1, 3, 6 and 12 months. Results All procedures had angiographically successful immediate outcome with
